All nations are initially Active. If they do nothing for
28 days, they cease to exist, vanishing
from the world to become a Former Nation. Former nations
(also sometimes called "ex-nations") can return to the world
by simply logging in.

Unless it was particularly large or notable, if a Former Nation
remains in that state for several years, its name becomes available
for reuse, which then allows a new nation to be created with the same
name. If this occurs, the Former Nation becomes Ancient and
cannot be restored.
